First of all, create db_schema.xml file inside /RH/Helloworld/etc and write the following code :



<?xml version="1.0"?>
<!--
/**
* Copyright © Magento, Inc. All rights reserved.
* See COPYING.txt for license details.
*/
-->
<schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">
<table name="rh_helloworld" resource="default" engine="innodb" comment="RH Helloworld">
<column xsi:type="smallint" name="id" padding="6" unsigned="false" nullable="false" identity="true" comment="ID"/>
<column xsi:type="varchar" name="author_name" nullable="false" length="25" comment="Name"/>
<column xsi:type="varchar" name="email" nullable="false" length="25" comment="Email"/>
<column xsi:type="varchar" name="description" nullable="false" length="255" comment="Descrition"/>
<constraint xsi:type="primary" name="PRIMARY">
<column name="id"/>
</constraint>
</table>
</schema>




  • <table> .. </table> = "Use for create and set table name"


  • <column> .. </column> = "Use for create and set column of the table"


  • <constraint> .. </constraint> = "Use for set constraint as like
    primary key, foreign key, unique key etc."


Before running the upgrade command you need to add your schema to db_whitelist_schema.json file by running the following command :



php bin/magento setup:db-declaration:generate-whitelist --module-name=RH_Helloworld


Now, there are db_whitelist_schema.json file will be create in /RH/Helloworld/etc folder.



Now, run php bin/magento s:up



Table will be create inside database.



=> If you want to renaming a column, you need to set below line in your db_schema.xml at appropriate column :



<column xsi:type="varchar" name="customer_email" onCreate="migrateDataFrom(email)" on_update="false" nullable="false" default="" comment="Customer Email"/>


here, name = "new column name" and onCreate="migrateDataFrom()" = "old column name"



=> If you want to drop table, then you can either remove entire table node from xml file or you can set disabled attribute to true as like below line in your db_schema.xml :



<table name="rh_helloworld" resource="default" engine="innodb" comment="RH Helloworld" disabled="true">
..
</table>


Hope, It will helpful for you.

Create file named as db_schema.xml under etc folder in your any custom module.



<?xml version="1.0" encoding="UTF-8"?>

<schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">
<table name="books_data" resource="default" engine="innodb" comment="Book Table">
<column xsi:type="smallint" name="id" padding="6" unsigned="false" nullable="false" identity="true" comment="BOOK ID"/>
<column xsi:type="varchar" name="book_name" nullable="false" length="255" comment="Book Name"/>
<column xsi:type="int" name="author" unsigned="true" nullable="true" identity="false" default="" comment="Author"/>
<column xsi:type="varchar" name="isbn_no" nullable="true" comment="ISBN No"/>
<column xsi:type="timestamp" name="publish_date" on_update="false" nullable="false" default="CURRENT_TIMESTAMP"
comment="Publish Date"/>
<column xsi:type="varchar" name="language" nullable="true" comment="Language"/>
<column xsi:type="decimal" name="mrp" scale="4" precision="12" unsigned="false" nullable="false"
default="0" comment="MRP"/>
<constraint xsi:type="primary" name="PRIMARY">
<column name="id"/>
</constraint>
</table>

<table name="author_data" resource="default" engine="innodb" comment="Author Table">
<column xsi:type="smallint" name="id" padding="6" unsigned="false" nullable="false" identity="true" comment="Author ID"/>
<column xsi:type="varchar" name="author_name" nullable="false" length="255" comment="Author Name"/>
<column xsi:type="varchar" name="author_email" nullable="false" length="255" comment="Author Email"/>
<column xsi:type="varchar" name="affliation" nullable="false" length="255" comment="Affliation"/>
<column xsi:type="int" name="age" unsigned="true" nullable="true" identity="false" default="" comment="Age"/>
<constraint xsi:type="primary" name="PRIMARY">
<column name="id"/>
</constraint>
</table>
</schema>


Now create db_whitelist_schema.json at same path



php bin/magento setup:db-declaration:generate-whitelist --module-name=Vendor_Module


After that just run php bin/magento setup:upgrade. For more information you can check Here . Let me know in case you need more explanation on this.

    Create file named as db_schema.xml under etc folder in your any custom module.



    <?xml version="1.0" encoding="UTF-8"?>

    <schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">

    <column xsi:type="int" name="author" unsigned="true" nullable="true" identity="false" default="" comment="Author"/>
    <column xsi:type="varchar" name="isbn_no" nullable="true" comment="ISBN No"/>
    <column xsi:type="timestamp" name="publish_date" on_update="false" nullable="false" default="CURRENT_TIMESTAMP"
    comment="Publish Date"/>
    <column xsi:type="varchar" name="language" nullable="true" comment="Language"/>
    <column xsi:type="decimal" name="mrp" scale="4" precision="12" unsigned="false" nullable="false"
    default="0" comment="MRP"/>
    <constraint xsi:type="primary" name="PRIMARY">

    </constraint>
    </table>

    <table name="author_data" resource="default" engine="innodb" comment="Author Table">

    <constraint xsi:type="primary" name="PRIMARY">
    <column name="id"/>
    </constraint>
    </table>
    </schema>


    Now create db_whitelist_schema.json at same path



    php bin/magento setup:db-declaration:generate-whitelist --module-name=Vendor_Module


    After that just run php bin/magento setup:upgrade. For more information you can check Here . Let me know in case you need more explanation on this.

      <constraint xsi:type="primary" name="PRIMARY">
      <column name="id"/>
      </constraint>
      </table>
      </schema>


      Now create db_whitelist_schema.json at same path



      php bin/magento setup:db-declaration:generate-whitelist --module-name=Vendor_Module


      After that just run php bin/magento setup:upgrade. For more information you can check Here . Let me know in case you need more explanation on this.
